Struct NonceState 

pub struct NonceState<'a> { /* private fields */ }

Typed, zero-copy view over an initialized durable-nonce account.

Implementations

impl<'a> NonceState<'a>

pub fn from_account_data(data: &'a [u8]) -> Result<NonceState<'a>, ProgramError>

Parse an initialized nonce account from raw account data.

Returns Err(InvalidAccountData) if the buffer is too short, the version is not Current, or the state is not Initialized.

pub fn authority(&self) -> &'a Address

The nonce authority allowed to advance/withdraw.

pub fn durable_nonce(&self) -> &'a [u8; 32]

The stored durable nonce (a recent blockhash, used as the tx nonce).

pub fn lamports_per_signature(&self) -> u64

The fee rate (lamports_per_signature) captured with the nonce.
